NEW PRODUCT – 3×4 Phone-style Matrix Keypad

Hey, Jenny, I’ve got your number! And I’m going to dial 867-5309 into this very nice phone-style matrix keypad. This keypad has 12 buttons, arranged in a telephone-line 3×4 grid. It’s made of plastic with sturdy plastic buttons. The keys are connected to a matrix so you only need 7 microcontroller pins (3-columns and 4-rows) to scan through the pad.

There’s a great Matrix Keypad Arduino library that should work great with this item with minor adjustments. It’s basically a sturdier version of our Membrane 3×4 Matrix Keypad and comes with 7 header pins pre-soldered on for easy plugging. Starting from the left there are three column pins, and then to the right are the four row pins.

In stock and shipping now!


Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
